SHOE SQLE AND HEEL.

Specification of Letters Patent.

liatented Dec. 21, 1920.

Application filed May 15, 1918. Serial No. 297,430.

To all? u; 7mm it may concern Be it known that I, Gnnran AJELLO, acitizen of United States, residing at New York, in the county of NewYork and State of New York, have invented a new Shoe Sole and Reel, ofwhich the following is a specificaticn.

The objects of my invention are: first to provide a sole that will berigid transversely while possessing the usual flexibilitylongitudinally; second, an impervious sole; third, a sole that wouldoutwear other parts of the shoe; fourth, a thin sole strongerthan thethick, bulky ones.

I attain these objects by the combination of parts illustrated in theaccompanying drawing, in which: Figure l is a longitudinal sectionalview of my sole attached to an ordinary shoe; Fig. 2 is a partiallongitudinal section of a similar sole; Fig. 3 is a partial elevationalview of an ordinary shoe with my sole attached thereto; Fig. at is across section of my sole attached to an ordinary shoe; Figs. 5 and 6 aresimilar sect-ions as Fig. 4 showing modifications; Fig. 7 is a plan viewof the outer face of the sole; Fig. 8 is a plan view ofa metallic partforming part of the new sole; Fig. 9 is an enlarged front view of aportion of Fig. 8 near one of its ends; Fig. 10 is a side view of thelatter.

Similar numerals refer to similar parts throughout the several views.

The new sole is composed of a corrugated sheetof metal 1; (shown inheavy line) surfaced with an outer layer of impervious, flexiblematerial 2, which can be provided with corrugations 3 or finished plainas at 41- (Fig. 2). The inside portions 5 of the corrugations could alsobe filled with the material 6 commonly employed to shape and receive theinner sole 7, if desired.

The impervious flexible material filling the corrugations 5, when sameas 2, can be connected, if desired, with the outer layer of the samematerial 2 by means of apertures 8 in the metallic member of the sole.(Fig. 8.)

A sole thus formed is attached to the ordinary shoe by means of theusual stitches 9 or other suitable means including metallic ones,through the holes or other kind of apertures 10 of the metallic sheet orplate. Said perforations are only provided on the upper and outerflanges 11 of the metallic plate according to the drawing; but if dehavepro ecting and upward bent ends 14,

which assist in the lateral end resistance of the sole.

If desired, the upper flanges 11 of the metallic plate could be extendedand bent over the edge of the sole, as illustrated at 15, Fig. 6.

it is obvious that, if desired, the metallic plate could also be used inconnection with an outer or lower sheet of leather in addition to theimpervious ply.

A. similar construction applied to the heel, as shown at 16, Fig. 1, hasa metallic member and finished outside surface substantially as shownrespectively in Fig. 8 and Fig. 7 the only variation from the sole beingthe outer line, which would take a contour typical of the usual heel. Inthis case, metallic connecting means the equal of nails, tacks or screwscould be inserted (in preference to stitches) through the perforations10, into the inner body of the heel.

In general, I do not wish to limit myself to the shown method ofattaching of the new solo or heel, as for example, a reinforcementconsisting of an extra piece of flexible material including leathercould be inserted around the edge; and, if desired, the metallic flangesll could be less projecting and without the perforations 10, so as toterminate all around just clear of attaching means 9 or the perforations10 could be wider, rectangular ones, spaced in relation to one anotherso as to clear the needle of the sewing machine.

I claim: I

1. T he herein described tread member for shoes comprising a metallicplate corrugated from one end to the other with the conrugationsextending transversely and from one side of the plate to the other, saidcorrugations being formed with flat bearing surfaces. I

2. The herein described tread member for shoes comprising a continuousimpervious metallic plate of spring metal, the same being corrugated,with the corrugations extending transversely thereof from one side tothe other, and comprising flat bearing surfaces.

3. In a tread for shoes, the combination of a metallic plate coextensivewith the forepart thereof and corrugated from one side to the other forlongitudinal flexibility and lateral rigidity, and an impervious ply ofmaterial coextensive with the corrugated plate and filling thecorrugations thereof along one surface.

at. In a shoe tread, the combination of a plate of sheet metalcoextensive with the tread and corrugated from one side to the other forflexibility in one direction and rigidity in the other direction, andimpervious plies of material fitted to both surfaces of the corrugatedplate and filling the corrugations thereof.

5. In a shoe tread, a metallic plate corrugated transversely thereof andfrom one end to the other, the ends of the bottom portion of eachcorrugation being flat and metallic plate corrugated from one end to theother and with the corrugations extending transversely of the plate forlateral rigidity, the bottoms of the corrugations nearest'the sole ofthe foot being provided with fiat end extensions having perforations forfastening purposes.

7. In a shoe tread, the combination of a metallic plate corrugated fromone end to the other, the corrugations extending transversely forlateral rigidity, the bottoms of all of the corrugations being providedwith free end members some of which constitute attaching means. andothers of which constitute lateral stiffening flanges, imperviousflexible material extending along the plate, and means serving to securethe metallic plate and the impervious material together and to the otherparts of the shoe.
